GENERAL DESCRIPTION
The SP769 is a linear low-side, constant-current driver designed to drive high power LEDs
from an input voltage rail. The driver acts as a current source, ensuring constant LED cur-
rent across a range of input voltages. The SP769 allows implementing the lowest cost LED
driver for a variety of applications. Internal circuitry maintains the preset constant current
output for a wide voltage range at the LED input. The LED current can be set at 200mA
at torch mode or 500mA (700mA SP7619A) at flash mode by selecting CTRL pin low/high
respectively. Dimming or shutdown can be done by feeding a PWM signal to the EN pin.
Fast EN turn-on/off time allows for very fast dimming frequencies, completely eliminating
flicker. The built-in thermal protection automatically stops LED current to prevent overheat-
ing. A timeout function serves as a fail safe, shutting down the output at 500mA (700mA)
current after 4 seconds of continuous operation if the enable input is not cycled. The Enable
pin should be cycled HIGH/LOW/HIGH to restart the driver.
